Täk? used to be close to #1 as far as Pittsburgh restaurants go, however it's tough to accommodate a vegan. Still they make the absolute BEST margarita in the city limits. Seriously fresh as can be, with every single ingredient made from scratch. And not loaded with artificial sugar. These are margaritas I can sip on and enjoy. The menu is always changing, with new items popping up monthly. You can never go wrong with their guacamole, and be sure to try all their house-made hot sauces --all a little different but so fresh and packing the perfect punch. Was sad when I found out their in-house flour taco shells are made with lard. Fortunately they have a vegan/gluten free corn shell to substitute with. They are able to accommodate a vegan with the mushroom taco, but you must omit the kale slaw, aioli, and substitute the corn shell. Waiter looked at me like I had three heads as I ordered - not running back here to spend my money.
